I had some big fubars around here, tryin’ to run audio stuff with everything being powered from the same battery.
I had to build a seperate power supply (panels, battery, charge controller) to operate my projection TV system. My head unit and the projector (which is connected to the main shack battery) had big issues thru the HDMI connection and I didn’t have any other way to isolate the two. The audio wasn’t an issue. I isolated with a isolation transformer but the video was all messed up. It was so bad that it would shut down the DVD player in the head unit! I’m just glad that I didn’t fry it..
My head unit..
A lot of money to fry over a ground loop..
